STANDARD TERMS AND CONDITIONS

Effective date: July 3, 2026 Last updated: July 3, 2026

These Terms and Conditions ("Terms") govern the use of this website, any related mobile applications, and the purchase of products or services from Rukavina Technologies LLC, a Texas limited liability company ("Company," "we," "us," or "our").

By accessing our website, using our applications, or purchasing our products or services, you agree to these Terms.

1. Services

The Company provides engineering design, consulting, development, and related professional services ("Services").

Unless otherwise agreed in a separate written agreement signed by both parties, all Services are provided:

  • On a time-and-materials or fixed-fee basis as specified in the applicable invoice or proposal
  • Based on information provided by the client
  • Without guarantee of any specific commercial outcome

Clients are responsible for reviewing and approving deliverables.

2. Products and Ordering

The Company may sell physical or digital products, including the RollerTrack sensor and related accessories.

All products are provided subject to availability, and we reserve the right to modify or discontinue products without notice. Product descriptions, images, and specifications are provided for general information and may contain errors; we do not warrant that they are complete, accurate, or current.

When you place an order through our online store, you make an offer to purchase. Your order is accepted only when we confirm it or ship the product. We may refuse, limit, or cancel any order, including where a product is unavailable or where a price or description was listed in error, in which case we will not charge you or will refund any amount already charged.

Prices are shown at checkout and may change without notice. You are responsible for reviewing and approving your order, and for the proper installation, configuration, and use of any product.

3. Payment Terms

For online store purchases, payment is due in full at checkout and is processed by our third-party payment processor, Stripe. By providing payment information, you represent that you are authorized to use the payment method.

For Services and other invoiced work, unless otherwise stated in writing:

  • Invoices are due upon receipt.
  • Late payments may accrue interest at the maximum rate permitted by Texas law.
  • The Company may suspend work or delivery for nonpayment.

You are responsible for all applicable taxes except those based on the Company's net income.

4. Shipping and Risk of Loss

We ship physical products to the address you provide at checkout. Shipping costs, if any, are calculated and shown at checkout before you pay; some products may ship at no cost to you. Delivery dates and shipping times are estimates only and are not guaranteed. You are responsible for providing an accurate shipping address; we are not responsible for delays or losses caused by an incorrect or incomplete address.

Risk of loss and title for physical products pass to you upon our delivery of the product to the carrier.

5. Returns and Refunds

Except for defective products covered under Section 6, physical products may be returned within thirty (30) days of delivery, provided they are unused and in their original condition and packaging.

To start a return, contact us at support@rukavinatechnologies.com to request a return authorization. You are responsible for return shipping costs for non-defective returns, and we recommend using a trackable method. Once we receive and inspect the returned product, we will refund the purchase price to your original payment method. Any original shipping charges are non-refundable.

Digital products and downloadable or app-based content are non-returnable and non-refundable once accessed or delivered, except where required by law or where the item is defective.

This return policy does not limit any rights you may have under applicable consumer-protection law.

6. Product Warranty

The Company warrants that its hardware products will be free from defects in materials and workmanship under normal use for the warranty period stated for the applicable product, which is one (1) year from the date of delivery for the RollerTrack sensor unless a different period is specified at the time of purchase.

If a covered defect appears within the applicable warranty period, contact us at support@rukavinatechnologies.com with proof of purchase. As your exclusive remedy, we will, at our option, repair the product, replace it, or refund the purchase price.

This warranty does not cover damage or failure resulting from misuse, accident, neglect, unauthorized modification or repair, improper installation, normal wear, or use outside the product's intended purpose. This warranty is non-transferable and applies only to the original purchaser.

Except for this express limited warranty, and except for any rights that cannot be waived under applicable law, products are otherwise provided as described in Section 7.

7. Disclaimer of Warranties

Except for the express limited warranty in Section 6, and except as otherwise stated in writing, Services, products, our website, and our applications are provided "as is" and "as available."

To the maximum extent permitted by law, the Company disclaims all implied warranties, including merchantability and fitness for a particular purpose. We do not warrant that our website or applications will be uninterrupted, error-free, or secure, or that any data, measurement, or output they produce will be accurate or reliable.

Engineering services involve technical judgment and uncertainty. No guarantee is made that deliverables will meet regulatory approval, commercial viability, or specific performance outcomes unless expressly stated in writing.

Nothing in this section limits any rights that cannot be waived under applicable consumer-protection law.

8. Intellectual Property

Unless otherwise agreed in writing:

  • The Company retains ownership of all pre-existing intellectual property, tools, processes, software, and know-how.
  • Custom work product is licensed to the client for its intended use upon full payment.
  • No intellectual property rights transfer until payment is received in full.

Website and mobile application content, including text, graphics, software, and branding, remain the property of the Company.

9. Website and Application Use

Users agree not to:

  • Use the website or application for unlawful purposes
  • Attempt to gain unauthorized access to systems
  • Interfere with the operation or security of the platform

We may modify or discontinue any part of the website or application at any time.

10. Mobile Application License

Subject to these Terms, the Company grants you a limited, personal, non-exclusive, non-transferable, revocable license to download and use our applications, including the RollerTrack application, on a device you own or control, for your own personal, non-commercial use.

You may not copy, modify, distribute, sell, lease, or reverse-engineer any application except to the extent that restriction is prohibited by law. Our applications are licensed, not sold.

If you download an application from a third-party app store (such as the Apple App Store or Google Play), your use is also subject to that store's standard end-user license agreement and terms. Where those terms conflict with these Terms as they relate to the application, the app store's standard end-user license agreement controls for that application. We may release updates to, or discontinue, our applications at any time.

Your privacy is addressed in our Privacy Policy, which explains how the application and website handle data.

11. Limitation of Liability

To the maximum extent permitted by law:

The Company's total liability arising out of or related to any product, service, website, or application shall not exceed the total amount paid by the customer to the Company for the specific product or service giving rise to the claim.

The Company shall not be liable for indirect, incidental, consequential, special, or punitive damages, including loss of profits, business interruption, or loss of data.

12. Indemnification

Client agrees to indemnify and hold harmless the Company from claims arising out of:

  • Client's misuse of deliverables
  • Modification of work product
  • Combination of deliverables with third-party systems not approved by the Company

13. Confidentiality

Each party agrees to maintain the confidentiality of non-public information disclosed during the course of Services unless otherwise agreed in writing.

14. Governing Law

These Terms are governed by the laws of the State of Texas, without regard to conflict of law principles.

Any disputes shall be resolved in the state or federal courts located in Texas.

15. Modifications

We may update these Terms from time to time. Continued use of our website, applications, products, or services constitutes acceptance of the updated Terms.
